Product Description:

The HDS03.2-W075N-HS24-01-FW is a modular amplifier unit introduced by Bosch Rexroth Indramat within the HDS Drive Controllers series. Designed for cabinet installation, the controller links servo axes to higher-level motion platforms and converts setpoint data into regulated output currents. Its role in industrial automation is to close the drive loop so that motors follow programmed profiles with minimal following error in printing, woodworking, and material-handling equipment. By processing encoder feedback in real time, the controller adjusts drive torque to counter load disturbances and help maintain positional accuracy during rapid indexing sequences. That closed-loop behavior supports stable speed and position control when machine loads change quickly. The controller is intended for modular drive cabinets where coordinated motion depends on fast current regulation.

The unit belongs to the DIAX04 platform, and its control bus uses the SERCOS fiber-optic ring to exchange real-time parameter data with the master. Within this architecture, the amplifier provides a continuous output of 75 A, allowing it to drive medium-power servo motors without external current boosters. Thermal stability is maintained by a built-in air blower that draws cabinet air across the heat sink, so separate ducting is not required. Continuous monitoring of heat sink temperature adjusts blower operation to keep semiconductor junctions within their permitted operating range during extended duty cycles. The fiber-optic link also supports synchronized command updates and status exchange across the drive system.

Production versions are identified by internal coding rather than separate option descriptions. This device is assigned to Line 03 and released as Version 2. Those identifiers indicate the product generation used for this controller. This release preserves pin compatibility with earlier models. It remains suited for cabinet-based multi-axis installations that use standardized drive modules.
